How long is the life of Stainless steel heating tube? First of all, this electric heating tube life does not mean how long the warranty of electric heating tube is. We know that warranty time does not represent the service life of tubular heating element. I believe that all of us will ask how long the heating tube warranty is when purchasing electric heating tube, so it does not mean that the heating tube must be broken when the warranty time is up, so we say that the warranty period of the heating tube does not represent the service life of the heating tube.
If the electric heating tube is done according to the production standard, the normal warranty is one year, and the warranty is not equal to the life of the heating tube. What are the factors that affect the life of the heating tube?
1. dry burning electric heating tube
The dry burning electric heating tube is based on the working temperature to select the appropriate heating tube material, the power needs to be reasonably designed according to the dry burning heating, there must be temperature control, and the dry burning electric heating tube also needs to pay attention to whether there is wind circulation, to meet the above conditions to ensure the life of the heating tube.
It should be noted that the gap between the mold aperture and the diameter of the heating tube is reasonable, generally the gap between the two is 0.1-0.2mm, if the gap between the aperture and the diameter of the tube is too large, it will affect the heat transfer between the electric heating tube and the module; If the gap between the aperture and the diameter of the tube is too small, it is not easy to take out the electric heating tube after heat expansion.
2. liquid electric heating tube
The life of the liquid electric heating tube is mainly related to the power design (surface load design), and the material selection of the liquid electric heating tube can be referred to – How to choose the material of the liquid electric heating tube shell? Attention! Dry burning can not occur in the heating area of the liquid electric heating tube, so when ordering the liquid electric heating tube, if the liquid level drops, it is necessary to inform the design cold zone in advance, so as to effectively control the life of the liquid electric heating tube.
The above content is an analysis of the life of the heating tube, and friends who need it can refer to understand.
